PATENT PORTABLE SELF-HEATING HOT-WATER, RADIATOR.

Application filed July 15,

To all whom it may concern:

Be it known that I, FRED CJ'BROWN, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented a new and useful Portable Self-Heating Hot-Water Badlato'r, of which the following is a specification.

This invention has reference to improvements in that type of portable radiators especially designed for heating rooms that have provision for holding a liquid fuel supply and are provided with thermostatic devices for regulating the feed of the fuel supply, and my said invention embodies, in a portable self-heating hot'water radiator, certain features of construction and novel combination of parts, all of which will be fully stated in the following detailed description, pointed out in the appended claims and illustrated in the accompanying drawing, in which: i I

Figure 1 is a vertical longitudinal section of a portable hot water radiator constructed in accordance with my invention, the fuel control valve devices and the thermostatic means for actuating the said valve devices being diagrammatically indicated. I

Figure 2 is an end elevation of my 1mproved radiator, the heating chamber and the water heating elements being shown in dotted lines.

Figure 3 is a verticalsection on a somewhat enlarged scale of the thermostatically controlled valve devices for controlling the fuel supply. In carrying out my invention, the radiator is substantially the usual standard shape audit is composed of a series of units that include two opposite end units 1-'1, which extend the full height of the radiator and whose lower ends terminate in bifurcations or foot members 1010 to each of which is connected a caster 11- 11 that provides-for conveniently moving the radiator from place to place.

22 designates a series of intermediate radiator units, the upper ends of which are in alignment with the tops of the end units 11 and the said upper ends of the intermediate units join with one another through the lateral passages 2020 in the solid or head portion 21 and which are in communication with the several intermediate radiator units, as shown.

It will be noticed by reference to Figure 1,

1921. Serial No. 485,017.

the lower ends of the intermediate radiator units'merge with a solid base portion 22 and the said lower ends of the said units 2 connect with one another and with the opposite end units 11 by the lateral passages 30 in the base portion22, as shown.

Thei'ntermediate radiator units 2 are of somewhat less height than the end units 1-1 whereby to provide ample space at the lower part of the radiator for a combustion or heating chamber 4 which, in the construction shown, is formed between a top section 40 "that merges with vertical end portions 41 which infturn merge with a bottom portion 42 that joins with the vertical portions i1 and has extensions id-A3 that merge with the end-units 11, as shown. .One of the end units 1, of my construction ofradiator, is, cast with a horizontal solid CllVlSlOIl 15, whereby an independent chamher 5 is provided at the upper end of the said unit,'whi'ch" chamber serves as a fuel holding compartment whenthe heating agent is a volatile fuel, as kerosene or gasoline, and which is delivered into the chamber through afedripe'rture 50 in the top thereof and which isnormally closed by a screw cap 16, asshown. The lower part of the said radiator unit 1 constitutes a water space which is in communication with the other legs or waterholding units of the radiator, as is clearly shown in Figure 1, by reference to which it will'be noticed the end unit 1, opposite the fuel holding unit, has afilling open- 'ing"17, at the top, through which the water is suppliedto the'radi'ator, which opening is normally closed" by a cap 18, it being understood thatwhen the radiator is filled with water, as'indicated, the water, as it is heated, is caused tocirculate through the radiator units in .the direction indicated by the arrows a. jTo observethe height of'the water within the radiator units, a gauge glass 19 is located near the upper end of the water receiving unit 1,and at a suitable point along the said water unit 1, is mounted a thermostat 6, which isdiagrammatically indicated, since the said thermostat may be of any well known construction, there being numerous types" of thermostats suitable for use in this connection, and therefore a detailed description or illustration of the thermostatic device is deemed unnecessary.

61 designate electric circuit wires from the opposing contacts of the thermostat 6 and they pass to a source of electrical energy, the cells or batteries 7, from which passes a circuit wire 62 that joins with the magnet 9. From the magnet 9 passes a line 63 back to the thermostat, as diagrammatically shown in Figure 3 of the drawings, which also illustrates the automatically operated valve control devices 8, presently explained in detail.

The heating element is a gas burner 65 of any approved type that is mounted on the bottom of the combustion chamber 1 and is suitably positioned for ejecting the fiame against the heating coil of water circulating pipes 10, the lowermost end 10 of which extends through one wall 4-1 of the chamber 4 and taps into the lower or water space and adjacent end radiator unit 1. The uppermost end of the water heating pipe coil passes through the other end a1 of the heating compartment 4 and connects with a ver tically extended pipe 11 that discharges into the adjacent end unit 1 near the upper or water inlet end thereof, and as clearly shown in the drawing.

12 designates a fuel. conveying pipe which communicates with the fuel holding cham her 5 and passes down and connects with the automatically regulated valve control 8, from which passes a pipe section 13 that communicates with and supplies the burner 65 which, in the practical development of my radiator is ignited by a simple pilot light of any suitable design that is kept burning so long as the radiator is in use.

1 1 designates a handle locatedon the out side of the radiator base and which is applied to the stem of a valve 15 located in the feed pipe 13' that extends from the automatic valve control casing to the burner 65 by which the fuel supply to the burner 65 may be cut off entirely when the radiator is not in use.

The thermostatic control device 8, hereinbefore referred to and illustrated in detail in Figure 3, comprises a suitable open top casing 80 that is located in the space between the radiator unit 1, in which is located the chamber 5 and the adjacent one of the short or intermediate units 2.

Within the casing 80 is mounted a post 81, upon which is supported an armature lever 82 that is pivoted at 83 and is normally shifted to its released position by a spring 84- that connects with the post 81 and the lever 82.

An armature plate 85 is attached to one end of the lever 82 and it cooperates with the magnet 9 which is energized through elriictrical connection with the batteries or ce ls 7.

The other end of the lever 82 carries a pendant latch member 86 that is adapted at times, as presently further stated, to engage a collar 91 on a stem 92 that carries a valve 93 and which is normally moved to its fluid passage closing position by spring 94 that is suitably mounted within the valve casing 95 and engages the valve 93, as shown.

96 designates a pivoted lever detent that is mounted on the valve casing and which drops under the the collar 91 on the valve stem and holds it up after it has been shifted to its uppermost position by thermostatic action until the magnet again responds to the thermostat and becomes ole-energized when the said latch device drops and catches under the member 96 of the lever 96, which lever is pulled and caused to disengage the collar 91 and release the valve 93 when the magnet again acts under thermostatic action, as the temperature of the water rises above the predetermined point and allows the valve 93 to instantly close under tension of its spring, at which position the parts remain until the magnet is further automatically energized, when the water cools down below the set temperature at which time the operation of lifting the valve 93 is repeated, as before stated.

. It is understood the thermostat operates to close the electric circuit from the cells to the magnet when it cools whereby to open the valves and it operates when heated to close the valve in a manner well known to those familiar with thermostatic control devices used in connection with fuel regulating valve mechanisms.

From the foregoing description, taken in connection with the drawings, the complete construction, the manner of its use and the advantages of my portable water radiator will be readily understood by those skilled inthe art to which my invention relates.

While the specific arrangement of the parts shown and described, presents a practical development of my improved selfheating portable radiator, it is to be understood that various details of construction and proportions of the parts may be varied or modified to meet the different requirements in the practical application of my invention without departing from the spirit thereof, as is set out in the appended claims.
